Time to pull the drums off and check for broken hardware or shoes down to nothing. S.O.P. is to inspect rear brakes whenever doing any brake work. I would not drive it until it gets looked at.

Had "the best" pads put on the front of our '93...I'm pretty sure ceramics...and have been listening to almost indicator on rotor like squealing ever since.

Haven't worn down much at all in 2 years, but good god does the noise get on my nerves at times...:annoyed:

Noisy brakes usually is caused by improper re surfacing of the rotor, depending on the type of pad used, there is a surfacing technique for that pad. the smoother the rotor surface the more prone to noise especially on light application. Drum brake noise is usually dust inside the drum or again the surface of the drum. I would seek out a brake specialty shop to re surface the rotors. Also any looseness of the pad within the caliper can cause noise. Make sure the shims behind the pads are there. I put black silicone on the pad backside when I install them so they will not move around. The more metallic the pad compostion, the more prone to noise. I have always used Delco brand pads on a GM car, Ford brand pads on a Ford product. Hope this helps. Also make sure the slide pins on the calipers are clean and lubed so the caliper moves in/out smoothly.

hey carnut. What would you use to lube the caliper slide pins. WD40, White litheum, etc.

Don't use any sort of spray lube, too thin. I would use a light application of high temp wheel bearing grease.
Just a dab 'll do ya! Spread it thinly and evenly on the pin.

By the way, the new pads should not squeal even if they are ceramic. If the rotors are freshly turned and either shims or adhesive was use on the pads they should break in nice and smooth and quiet. If the rotors were not turned or were glassy smooth you can expect them to squeal. If the pads are making noise I would pull them off and scuff them lightly to allow them to break in with the rotors.

I don't use the ceramic pads because I don't run extended speeds over 85 mph and I use the engine and tranny to keep speed down on long, steep inclines. They have a tendency to wear the rotors out.

There is a silicone clear grease made just for doing this. It wont melt with the heat generated.
